My apologies to Planespeaking for the previous identity error.
So SWBKCB, the terminal was "empty" was it when the surveys were carried out which endowed SEN with 'best London airport' status? I think not and wonder when you last travelled through SEN because when I used it several times last summer (and oh, how long ago that seems now!) it was very busy each time. Three gates at SEN? More than double that I think but don't let that get in the way of your agenda. Yes, of course SEN will struggle to regain momentum and probably the larger airports will be the beneficiaries of the consolidation of routes by the "big boys", but that's a consequence of COVID-19 and not through SEN's inherent shortcomings and surely many other smaller airports will suffer likewise.
